Ian Lance Taylor <ian at airs dot com> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |ian at airs dot com --- Comment #1 from Ian Lance Taylor <ian at airs dot com> --- Revision 249111 introduced the test, so evidently the test never worked on PPC64. But I don't know why. You should find a ttest program in your working directory, and presumably running that program will fail as shown below. Can you disassemble the functions test1_thread, f2, and f3 from that program and post the disassembly here?
